public class ServletWrappingController extends AbstractController implements cn.taketoday.beans.factory.BeanNameAware, cn.taketoday.beans.factory.InitializingBean, cn.taketoday.beans.factory.DisposableBean, ServletContextAware
Framework Controller implementation that wraps a servlet instance which it manages internally. Such a wrapped servlet is not known outside of this controller; its entire lifecycle is covered here (in contrast to ServletForwardingController).

Useful to invoke an existing servlet via Framework's dispatching infrastructure, for example to apply Framework HandlerInterceptors to its requests.

Note that Struts has a special requirement in that it parses web.xml to find its servlet mapping. Therefore, you need to specify the DispatcherServlet's servlet name as "servletName" on this controller, so that Struts finds the DispatcherServlet's mapping (thinking that it refers to the ActionServlet).

Example: a DispatcherServlet XML context, forwarding "*.do" to the Struts ActionServlet wrapped by a ServletWrappingController. All such requests will go through the configured HandlerInterceptor chain (e.g. an OpenSessionInViewInterceptor). From the Struts point of view, everything will work as usual.

      public void afterPropertiesSet() throws Exception
      Initialize the wrapped Servlet instance.

    • setServletContext

      public void setServletContext(ServletContext servletContext)
      从接口复制的说明: ServletContextAware
      Set the ServletContext that this object runs in.

      Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.

      指定者:
      setServletContext 在接口中 ServletContextAware
      参数:
      servletContext - the ServletContext object to be used by this object
